This is a new hardware monitoring driver, w83627ehf, which supports the Winbond W83627EHF Super-I/O chip. The driver is not complete, but already usable. It only implements fan speed and temperature monitoring, while the chip also supports voltage inputs with VID, PWM output and temperature sensor selection. I have no more time to work on this, but anyone with supported hardware could add the missing functionalities later. This driver is largely derived from the w83627hf driver. Thanks to Leon Moonen and Steve Cliffe for tesing the preliminary versions of my driver and reporting the problems they encountered. Thanks to Grant Coady for noticing and fixing various corner cases in the fan management. This third version of the driver hopefully addresses all the issues the original version had. Signed-off-by:

Hi Alexey, > Files that don't use CONFIG_* stuff shouldn't include config.h > Files that use CONFIG_* stuff should include config.h > > It's that simple. ;-) I agree. This won't change anything though, as all drivers include either device.h or module.h, which in turn include config.h. But you are still correct, so I approve your patch. For completeness, I would propose the following on top of your own patch: i2c bus drivers do not need to define DEBUG themselves, as the Kconfig system takes care of it. Signed-off-by:

On top of my previous patch which removes the use of address ranges in video i2c drivers, this one can save an additional few bytes of memory. Most of these drivers which do not use I2C_CLIENT_INSMOD initialize the unused address lists in a less than optimal way. This patch simply optimizes this, by using a single one-element list instead of 3 different lists with two elements each. This saves an average 63 bytes on these drivers. Signed-off-by:

Some months ago, you killed the address ranges mechanism from all sensors i2c chip drivers (both the module parameters and the in-code address lists). I think it was a very good move, as the ranges can easily be replaced by individual addresses, and this allowed for significant cleanups in the i2c core (let alone the impressive size shrink for all these drivers). Unfortunately you did not do the same for non-sensors i2c chip drivers. These need the address ranges even less, so we could get rid of the ranges here as well for another significant i2c core cleanup. Here comes a patch which does just that. Since the process is exactly the same as what you did for the other drivers set already, I did not split this one in parts. A documentation update is included. The change saves 308 bytes in the i2c core, and an average 1382 bytes for chip drivers which use I2C_CLIENT_INSMOD, 126 bytes for those which do not. This change is required if we want to merge the sensors and non-sensors i2c code (and we want to do this). Signed-off-by:

This patch removes some unneeded checks of pointers being NULL before calling kfree() on them. kfree() handles NULL pointers just fine, checking first is pointless. Signed-off-by:

Due to the use of write-behind, it is possible for md to write a page to the bitmap file that is still completing writeback. This is not allowed. With this patch, we detect those cases and either force a sync write, or back off and try later, as appropriate. Signed-off-by:

1/ Must typecast int to (sector_t) before inverting or we might not invert enough bits. 2/ When "bitmap_offset" was added to mdp_superblock_1, we didn't increase the count of words-used (96 to 100). Signed-off-by:

currently, md updates all superblocks (one on each device) in series. It waits for one write to complete before starting the next. This isn't a big problem as superblock updates don't happen that often. However it is neater to do it in parallel, and if the drives in the array have gone to "sleep" after a period of idleness, then waking them is parallel is faster (and someone else should be worrying about power drain). Futher, we will need parallel superblock updates for a future patch which keeps the intent-logging bitmap near the superblock. Also remove the silly code that retired superblock updates 100 times. This simply never made sense. Signed-off-by:

This provides an alternate to storing the bitmap in a separate file. The bitmap can be stored at a given offset from the superblock. Obviously the creator of the array must make sure this doesn't intersect with data.... After is good for version-0.90 superblocks. Signed-off-by:

Before completing a 'write' the md superblock might need to be updated. This is best done by the md_thread. The current code schedules this up and queues the write request for later handling by the md_thread. However some personalities (Raid5/raid6) will deadlock if the md_thread tries to submit requests to its own array. So this patch changes things so the processes submitting the request waits for the superblock to be written and then submits the request itself. This fixes a recently-created deadlock in raid5/raid6 Signed-off-by:

When an array is degraded, bit in the intent-bitmap are never cleared. So if a recently failed drive is re-added, we only need to reconstruct the block that are still reflected in the bitmap. This patch adds support for this re-adding. Signed-off-by:

When looking for pages that need cleaning we skip pages that don't have BITMAP_PAGE_CLEAN set. But if it is the 'current' page we will have cleared that bit ourselves, so skipping it is wrong. So: move the 'skip this page' inside 'if page != lastpage'. Also fold call of file_page_offset into the one place where the value (bit) is used. Signed-off-by:

Currently we don't wait for updates to the bitmap to be flushed to disk properly. The infrastructure all there, but it isn't being used.... A separate kernel thread (bitmap_writeback_daemon) is needed to wait for each page as we cannot get callbacks when a page write completes. Signed-off-by:

As the array-wide clean bit (in the superblock) is set more agressively than the bits in the bitmap are cleared, it is possible to have an array which is clean despite there being bits set in the bitmap. These bits will currently never get cleared, as they can only be cleared by a resync pass, which never happens. No, when reading bits from disk, be aware of whether the whole array is known to be in sync, and act accordingly. Signed-off-by:
